How do you solve 5v/13=25/39

Answers

Solving a Single Variable Equation :

 2.3      Solve  :    3v-5 = 0 

 Add  5  to both sides of the equation : 
                      3v = 5 
Divide both sides of the equation by 3:
                     v = 5/3 = 1.667 


One solution was found :                   v = 5/3 = 1.667
Making Equivalent Fractions : 1.3      Rewrite the two fractions into equivalent fractions

Two fractions are called equivalent if they have the same numeric value.

For example :  1/2   and  2/4  are equivalent,  y/(y+1)2   and  (y2+y)/(y+1)3  are equivalent as well. 

To calculate equivalent fraction , multiply the Numerator of each fraction, by its respectiveMultiplier. L. Mult. • L. Num. 5v • 3—————————————————— = ——————L.C.M 39R. Mult. • R. Num. 25—————————————————— = ——          L.C.M 39Calculating the Least Common Multiple : 1.1    Find the Least Common Multiple 

      The left denominator is :       13 

      The right denominator is :       39

      Least Common Multiple:

rearrange = 5*v/13-(25/39)=0 

Step by step solution:part 1: 5v 25 Simplify —— - —— 13 39

Calculating Multipliers : 1.2    Calculate multipliers for the two fractions 


    Denote the Least Common Multiple by  L.C.M 
    Denote the Left Multiplier by  Left_M 
    Denote the Right Multiplier by  Right_M 
    Denote the Left Deniminator by  L_Deno 
    Denote the Right Multiplier by  R_Deno 

   Left_M = L.C.M / L_Deno = 3

   Right_M = L.C.M / R_Deno = 1

Pulling out like terms : 1.5     Pull out like factors :

   15v - 25  =   5 • (3v - 5) 
Equation at the end of step  1  : 5 • (3v - 5)———————————— = 039
Step  2  : 5•(3v-5)Solve ———————— = 039

A circular Petri dish has a diameter of 10 centimeters. If the dish contains 2.450 bacteria, what is thepopulation density of bacteria in the dish?
(1) 31 bacteria per square centimeter
(2) 42 bacteria per square
centimeter
(3) 48 bacteria per square centimeter
(4) 51 bacteria per square centimeter​

Answers

Answer:  31 bacteria per square centimiter.

Step-by-step explanation:

The correct number of bacteria in the question is 2,450.

Hi, to answer this question we have to apply the next formula:

Area of a circle = π x (diameter/2) ^2

Replacing with the values given:

A = π x (10/2) ^2

A = π x (5) ^2

A = π x 25 = 78.54 cm2

Next, we have to divide the number of bacteria (2,450) by the area of the dish  

2450 / 78.54 = 31.19 = 31 bacteria per square centimiter.

Feel free to ask for more if needed or if you did not understand something.  

Emilio paid $287.50 in taxes to the school district that he lives in this year. This year’s taxes were a 15% increase from last year. What did Emilio pay in school taxes last year? PLEASE HELP

Answers

Let the Taxes she paid last year be 'x'
So percentage increase = 15% of x
= 15x/100

So,
this year's taxes = Last year's taxes + increment
287.50 = x + 15x/100
287.5 = 115x/100
x = 250

So, she paid $250 as taxes last year.
